Can anyone tell me if XM Radio works in Alaska? I read in some old posts that XM had quite a few problems but Sirrius worked pretty good. Since those posts, the two companies have merged. A group of 9 of us are getting off the Alaska Ferry in Skagway on June 12th, heading for Fairbanks, Denali, and then back to Washington over a 2+ week period. A few tunes might augment the great experience we're all expecting. Thanks for your help.
